Former “Son of Guns” star Will Hayden‘s oldest daughter, Stephanie, is speaking out about suffering sexual assault at the hands of her father.

When asked why she decided to reveal the abuse now, Stephanie told Dr. Phil (via TMZ), “Because I know, that for one, my sister needs me. She needs someone who can speak for her, that can be on her side. That’s the main reason.”

She added, “Also, I have a responsibility. I am in the public eye. There are little girls all over this world and I need them to know that there is a way that you can tell someone and they will help you.”

Hayden was arrested last month on child molestation and aggravated crime against nature charges. He is currently incarcerated.
